Cozumel’s tropical climate makes for an ideal backdrop to a vacation filled with sun, sand, and sea. While I like to think there’s no bad time to visit the island, weather in Cozumel can involve tropical storms, extreme heat, and even the possibility of a hurricane. If you’re in search of a holiday with the least chance of rain and unpredictable weather, there are certain periods you should avoid.

Read on to find out about common weather patterns in Cozumel spread across the seasons along with a month-by-month analysis of what to expect during your trip.

Understanding Cozumel Weather

The weather in Cozumel can be split into two main seasons: the dry season from December to April and the wet season from May to November.

The dry season coincides with what amounts to winter here in Cozumel and you can expect an average temperature of 75°F. The wet season marks the rainiest months of the year when you can experience up to 9.5in of rain in one month. The wet season is also the warmest time of the year and on its hottest days, the Cozumel temperature rises to as high as 93°F or more.

Along with the wet and dry seasons, Cozumel also has two other unique seasonal factors to be aware of. The hurricane season occurs between June to November with the highest chance of storms from August to October. While the idea of a hurricane can be alarming, the last serious hurricane to hit the island was in 2005. Since then we’ve had a smattering of tropical storms and lower category hurricanes, but nothing the island hasn’t been prepared to handle.

“Norte” season is likely a new one for you and it’s not something I expected to encounter when I moved to a holiday destination in the Caribbean. I knew it could get cooler in the winter but I never quite expected the cold that can quickly appear during a "norte".

A norte is a cold front where winds come in from the north and cool the entire region down. The season occurs from November through February and usually occurs for a week or two at a time. While you might notice the locals decked out in jackets and scarfs as if they’re headed to a snow season in Whistler, the coldest you can expect is a dip to 66°F in the evenings. Daytime temperatures in the 70-80s mean you can still enjoy a day at the beach without feeling too chilly, but if you’re planning a visit to the island during the norte season, be prepared with some layers and a light jacket or windbreaker.

The biggest concern with norte season is the winds which could keep the snorkel and dive boats docked due to the choppy waves. On particularly windy days, my top tip is to plan any activities later in the day when it’s more likely to be warmer and avoid the east side of the island which gets the brunt of the wind. Even better, spend the day exploring Cozumel’s downtown with a food tour or tequila tasting or head under the sea where it’s calm on the Altantis Submarine!

The water temperature is usually cool in the morning but warms up to be much more comfortable in the afternoons.

April is another close to perfect month in Cozumel, both weather-wise and due to the notable drop in visitors to the island during the latter part of the month.

The rain takes a bit of a break this month but temperatures stay mostly the same as June. Holiday-goers looking for a summer escape are actually on to a winner here because while there is still a chance of rain 11 days out of the month, the precipitation actually drops down to 3.5in. And when it does rain, it comes as a relief from the heat of the day, making an expedition by jeep through the Cozumel jungle even more of an adventure.

Avoid the heat by soaking in a pool or the ocean from noon to 4:00 PM when temperatures are the hottest.

What is the Weather Like in August in Cozumel?

Visitors planning a trip during August can expect average highs of 89°F and lows of 73°F with a similar amount of rain as July.

What is Cozumel Weather Like in September?

September and October mark the height of the wet season and when Cozumel gets the most amount of rain: an average of 5.5 inches and almost 16 days of precipitation. The rain tends to come and go fairly quickly so outdoor activities are still possible and if you are unlucky and face the chance of a full day of rain, you can try something unique like a trip down below on an Atlantis Submarine. Cozumel weather in September is tricky but if you do risk the rain, you’ll get to enjoy the island at one of the quietest periods for tourism.

The October weather conditions are very similar to September, although the temperature and rains decrease a bit. Previous trends show an average of 5.6in of rain with highs of 86°F and lows of 72°F.
